What's after outer space?

Here's something I've thought about many times and never come up with a good answer for...

What's after outer space? If you think about it, you'll probably come to the conclusion that "nothing" is after space. Suppose you start at Earth and you could keep moving further and further away from Earth as fast as you wanted to. First you would see the moon, then other planets, then once you get of our solar system you'd see other solar systems, and then other galaxies, and then the whole universe with all of the galaxies in it,....and then what? Nothing? But isn't space "nothing?" I mean I know there are subatomic particles and random atoms of nitrogen and other elements scattered throughout space so it's not completely empty. So that means there is still something in space, even in outer space there's something even if it's just one atom every 100 billion miles or so. But what is it after you get past where the last atom of anything is? What is it when there is truly nothing anymore (except you of course if you were there hypothetically). Is that space too? If so, what if you keep going further and further anyway....is there an end somewhere, where it turns into something else?
I've read stuff by Stephen Hawking and other physicists that theorize that matter and time are related so really the four dimensions we all know (x,y,z, and time) are all connected together and influence each other. So if that's true, there must be an end to space right? Because if you believe in the big bang theory like I do (the basics of it, which doesn't make it necessary to deny creationism is true), then there was a beginning to space and time. And since there is a beginning and the universe has been expanding since that point (or maybe is contracting again now depending on what you might believe about the different theories that are out there), then there must be an outer edge somewhere. So what if you reached that outer edge? Would you be outside of time then too? And if you were, then there would be no dimensions either because they are all connected. So you really couldn't be there at all since you are a three dimensional thing. So there really is "nothing" after space, because there can't be right? So then what would happen if you were at the edge of space and you threw a ball past the edge? Would it just dissapear? If so, then that would break Einstein's  law of conservation of mass and energy? Or I guess maybe it wouldn't just cease to exist, but it could be transformed into some kind of energy. So then even if that happened, there would then be something in the "nothing," so that would be an extension of space right? So then if that were true, then there would be the three spatial dimensions and the dimension of time in that extension of space too, so would the ball reappear or stay energy? Or would that not happen at all and instead when you tried to throw the ball out past the edge of space, would the edge of the ball just push the edge of space out with it so it would never dissappear or transform into energy in the first place? And if that were the case, what if you could throw the ball faster than the speed of light? Would the edge of space be able to keep up with the front edge of the ball? Or maybe that's totally impossible anyway because if you threw the ball faster than the speed of light then it would turn into a black hole or something crazy like that. 

Yeah,....I don't know. But I still wonder what is after space...if anything...and what would happen if you got there and threw a ball past the edge.

What do you think?

I like this post for the sheer wonder of it. "What's after outer space?" is after all, a loaded question. What's "after"? What's "space"?

Quite to the contrary, I don't think of "space" as "nothing," but indeed "something". Something spectacular, in fact.

What's more, putting yourself in the middle of the absence of space poses some interesting problems! But without any concrete knowledge, who knows if space, as we think of it, is finite or not.

Maybe you'd throw the ball and it would hit you in the back of your head. Or perhaps it would hit me, even though I was in another dimension! Or maybe Charles Darwin would catch it and ask his good friend Jesus Christ if he wanted to play catch?

The best thing about science is the never-ending questions.

There's 7 skies and earth consists of 7 layer, from the core to the atmosphere, so do the space out there, then it will take us a long way to heaven & hell. Earth is just like a finger-ring on a wide desert, so imagine how huge the universe is.
